General Hotel Notes

• With the completion of the Marriott renovations in 2008, the Hyatt and Marriott Marquis are typically the busiest hotels.
• The Hyatt is the hotel that will typically run into issues with the fire marshal. If large crowds are not your thing, you might consider spending more time in the Marriott or the other hotels. It is not uncommon for there to be literally thousands of people in the Hyatt lobby from time to time.
• The Hyatt has five elevators in the main part of the hotel. If you choose to use these, you will be able to get to know all of the other people that are waiting quite well - elevator waits can take more than 30 minutes to go up to your room. Plan accordingly - the Hyatt is not the hotel where you should expect to run to your room every fifteen minutes. Whenever possible, take the stairs.
• For social smokers, the Hyatt pool is the place to be.
• Checking out of a Dragon*Con primary hotel on Monday morning is a special experience. You really should consider moving your belongings out on Sunday, or early Monday morning, or plan to have a bellhop deal with it for you (which might take several hours). While Dragon*Con is a special place for you and tens of thousands of your best friends, we are also all checking out at once, and this tends to overwhelm the host hotels year after year.

• Moving between the Marriott Marquis and the Hyatt is pretty easy - usually. As long as you have a Dragon*Con badge, you can walk out the front entrance of the Marriott, cross the street (an APD uniformed officer is typically there acting as a crossing guard), and walk up the rear (pool) entrance of the Hyatt, and vice versa. Inevitably, this gets shut down at some point, when capacity issues come to a head, which might mean that you'll need to actually walk "around" the Hyatt.
• NEVER leave your hotel without your room key and Dragon*Con badge. When you try to take shortcuts (i.e. the Hyatt pool entrance), D*C security needs to see your badge. When the fire marshal shuts down entry to the Hyatt, entry opens up first to those with room keys. You could be locked out of the Hyatt for 90 minutes, or longer, if you aren't prepared.
